Do you have sash guides for these windows?

Hello,

Take a look at our S350-28 channel balance and follow the chart under the product description that explains how to confirm the correct strength option based on the sash weight. 

Also, we do carry top sash guides as well but we would need to see an undamaged part removed from your window sash, along with dimensions, to recommend one for your window. Thank you!
